Safety and environmental protection

A combustion engine must operate in a certain temperature window in order to function optimally. To prevent the engine from overheating and causing serious damage to the mechanics, the heat generated by the engine cooling system during engine operation must be effectively dissipated to the environment.

In order to meet the high requirements for safety, comfort and economy, almost no sub-assembly gets by without electronic control anymore. This can also be seen in the cooling system, which ensures perfect and efficient engine operation thanks to ingenious thermo management.

Thermal management fulfils the essential task of ensuring engine functionality in all operating and weather conditions.

Thanks to the cooling circuit it prevents overheating and, on the other hand, ensures that the engine quickly reaches the required operating temperature. This ensures that as little pollutants as possible are generated during combustion in the engine compartment.

In order to ensure reliable engine thermal management, the maintenance intervals prescribed by the vehicle manufacturer should be strictly adhered to. Correspondingly, great emphasis should also be placed on quality in this area.

febi bilstein offers a comprehensive range of products in the field of engine thermal management in tested original equipment quality. These include thermostats, viscous couplings, cooling expansion tanks and water pumps.

THE ADVANTAGES AT A GLANCE

Long service life

Strict quality standards

Precision fit

Compliance with the
requirements of vehicle manufacturers

Switched water pumps

EFFICIANT INNOVATION

If the vehicle is cold when started, no cooling is required. However, higher cooling performance is required when the engine is subjected to high loads. Sensors detect the vehicle status and the engine management unit then calculates the necessary cooling power.

The electromagnetic water pump allows this custom control, adapted to the cooling performance required by the situation. Depending on the vehicle, up to 1.5 percent fuel can be saved this way. In addition, the environment is also saved, since the emission limits for the Euro 5 and Euro 6 exhaust standards can be achieved.

Switched water pumps also have other advantages. If the water pump is not needed and its output is reduced by up to 50 percent, the energy consumption is correspondingly lower. Thus the saved engine power is available for the drivetrain or other consumption. Conventional, non-switched water pumps, on the other hand, always run at full power.

High performance for a perfectly running engine

The water pump must operate at maximum performance in every vehicle. Only optimal coolant circulation ensures the perfect operation of the engine.

This is why febi bilstein relies on its know-how as a manufacturer for this important product group.

Nearly 10,000 commercial water pumps are manufactured annually on modern, CNC machines in our own production plant near the company headquarters in Ennepetal.

This makes up about 15 percent of the complete water pump range offered by febi bilstein.

Viscous Clutch: For fresh air

The Viscous Clutch is an important component for vehicle cooling. In older vehicles, there are still Visco Clutches that are not electronically controlled.

They consist of two discs, between which there is liquid (silicone oil). One disc is driven by the engine, the other is connected to the Visco wing. If cooling is required, a bimetallic spring ensures that the liquid between the discs is transferred by adhesion to the other disc.

The more modern version is an electronically controlled viscous coupling. It is similar in construction, but the fine regulation of the engine control unit replaces the rough regulation of the bimetallic spring. This saves fuel and relieves the environment.
